Answer:
Explanation:
Hello!
In this case, according to the reaction:
We can see there is a 4:2 mole ratio between chromium and chromium (III) oxide, this, for the given 56.2 g of chromium, the theoretical yield of the oxide product is computed down below:
Now, considering the 76.0-% yield for this reaction, the actual yield turns out:
Best regards!
Answer:
455.4 mmHg
Explanation:
To solve this problem we can use <em>Gay Lussac's Law</em>, which describe the temperature and pressure of a gas, at constant volume and composition:
In this case:
We <u>input the data</u>:
- 621 mmHg * 231 K = P₂ * 315 K
And <u>solve for P₂</u>:
They are Acids
when acids are in water they dissociate and release H+ ions into the water
while bases release OH- ions
hope that helps
Answer:
b 1 mole of nitrogen 6 hydro 1 sulfur
Answer:
The answer is rather simple, if you understand electron configurations: the shape of the periodic table mimics the filling of the subshells with electrons. The shape of the periodic table mimics the filling of the subshells with electrons. ... The next two electrons, for Li and Be, would go into the 2s subshell.
